The Lowdown
Alright folks, Rusty here, looking at our little slice of the coast at Jaconé. The next couple of weeks are a mixed bag, so let's sift through the noise and find the windows where it's worth paddling out.
We've got water temps sitting at a very comfortable 72°F, which is pretty standard for this time of year, nothing weird going on there. The start is a bit of a write-off, though. Sunday and Monday morning are a mess with that southerly wind and short-period, choppy swell. You can forget about it. The first real glimmer comes Monday afternoon. The wind swings around to a light easterly, going cross-offshore, and we get a 8ft SSW groundswell at a solid 10 seconds. The wave energy is dialed in at (1120) – moderate to strong. It's going to be clean and have some push. This is a solid afternoon session for experienced surfers, the kind where you can actually carve.
Tuesday looks pretty good too. Early morning we get a clean, offshore north-easterly breeze with a 5ft S swell. It's clean and workable, a good one for the intermediate crew to get amongst it. The energy is still decent at (645). The stand-out of this first week, though, has to be Monday afternoon. That bigger, cleaner swell with the right wind is the best we’ll see for a few days.
Things go quiet mid-week with the swell dropping right off, but hold tight. A bigger pulse is showing for the following Monday, the 14th of September. That morning we’ve got a moderate offshore from the ENE and a 4ft S swell. The wave energy is ramping back up to (570). The afternoon gets even better – the wind stays offshore from the NE and the swell jumps to 6ft from the SSE. That’s the best combination of the whole forecast period. It’s going to be clean, hollow, and have proper power behind it. A real highlight.
We then get a few more days of clean but smaller surf before a big one pops up on Friday the 18th. The forecast is showing a massive 10ft ESE swell rolling in, carrying a whopping (2270) of combined energy. That’s strong, serious stuff. The wind is cross-off and clean, but a 10ft swell at Jaconé is only for the real experts. Beginners, stay on the beach for this one. If you’re a strong surfer, that Friday morning session is a monster waiting to happen.
The weekend after that cleans up a bit. The 19th of September has a clean, moderate offshore with a 5ft SSW groundswell (816 energy). It’s a solid, powerful option. Then the 20th gets a bit weird with a short-period 6ft ENE swell, which is less appealing.
So, to keep it simple: Monday 7th afternoon is your first quality session, and the true standout are the Monday 14th and Tuesday 15th windows, especially the Monday afternoon. That’s the one with the best lineup of clean wind, solid size, and decent energy. The big 10ft day on Friday the 18th is a massive bonus for the expert crew only. The rest of the time, you're hunting for small clean windows in the mornings. Keep your wetsuit ready.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
